At least three clumps of loosestrife along the Johnson creek. One by the marker I placed on map. The other two I saw are clearly visible down stream from the first.

None

Location

I saw purple loosestrife along the Johnson creek. I saw it in at least three locations down the creek. It's located within that section of the creek with that has trails going through it right by the water. It's flowering right now.
